IMPROVEMENT l N GALVANlZlNG-MACHINES..

Y Specification forming part of Letters Patent No. l80,l82 dated July25, 1876; application filed To all whom it may concern Be it known thatI, GEORGE E. A'OHESON, of the city and county of Philadelphia,- andState of Pennsylvania, have invented a new andImprovedGalvanizing-Machine, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a vertical longitudinalsection of my improved galvanizing-machine, taken on line 00 m, Fig. 2;Fig. 2 is a vertical transverse section of the same on line y 3 Fig. l;and Fig. 3, a; detail vertical central section of the detachable rolleron which the wire-cloth is wound.

Similar letters of reference indicate corresponding parts.

The invention relates to an improved machine for galvanizing or paintingwire-cloth in such a manner that no surplus metal, liquid, or paintremains on the cloth, that no scum is taken up by the same, and,finally, the winding-up roller may be easily removed from the wire-clothafter the galvanizing'or painting process is completed.

The invention consists of a machine with rollers for tigh tening-thewire-cloth while passing through the galvanizing or painting liquid.Suitable skimmers and heaters are arranged in connection with the clothat both sides of the same, to secure the regular tinnin g or painting. Asectional and diagonallyjointed winding-up roller serves for beingreadily taken out of the cloth.

In the drawing, Airepresents a receptacle for the galvanizing orpainting liquid, on which is supported a suitable frame-work, B, towhich the different operating parts are applied. The wire-cloth isguided over tightening-rollers D D D, of which the front one, D, servesto guide the cloth from the roll to a lowerroller,

D that is submerged in the galvanizing-liquid, and adjusted therein bysliding supporting-rods B of frame B to greater or less depth, accordingto the quantityof liquid in the receptacle and the degree of stretchingor tightening required.

The wire-cloth passes from the lower roller D to the upper roller D?, towhich it is securely clamped to be wound upon the same.

The upper roller D is revolved by a crank in top hearing of frame B, andmade of two diagonally-separated sections,D ,-that are connected byinterior recesses a, a fixed screwnut, b, and the threaded 'end of therollersliaft having a collar, 61, as shown in detail in Fig. 3.

By turning the rollerrshaft in one direction, the diagonal sections Dare screwed together,

and firmly retained by end hoops or bands 6 at the ends of the sectionsD By turning the shaft in opposite direction, the sections maybedetached and readily-taken out of the roll of wire-cloth wound aroundthe same.

The sectional roller D is, for this purpose,

The skimmers E are operated by intermeshing wheels and pulley and beltor. chain con nection with the gear-wheels of the-windingup roller DThey are made of swinging plates, that are hung to-revolving'arms orendless belts, or similar devices, asdesired. The shimmers enter. theliquid atboth sides of the wire-cloth, and carry off any froth or scumthat accumulates on the surface of the liquid, preventing the contact ofthe scum with the wire-cloth. The wire-cloth is thereby brought incontact with clear metal or paint in entering and leaving the liquid,and is thus galvanized or painted by mechanical means in a perfect,economical, and effective manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A machine for galvanizing or painting wire-cloth,consisting of rollers for guiding, tightening, and winding up thewire-cloth, in connection with reciprocating heaters .and skimmersarranged at each side of the wirecloth, substantially in the mannerdescribed, and for the purpose specified.

2. The winding-up roller 1), made in two diagonal sections, connected byinterior recesses, fixed nuts, and threaded end of rollersllaft, asshown and described.

3. In a galvanizing-nnwiline, the swinging reciprocating heaters,striking alternately each side of the Wire-cloth to remove the surplusliquid, substantially as specified. i

4. In a galvanizingmachine, the pendent revolving Skimmers, entering theliquid at both sides of the \vire-el0tll,-t0 keepthe sztnle clear ofscum, substantially as described.
